The URL cydia.invoxiplaygames.uk/certificates/ is a critical resource used by the legacy jailbreak community to fix connection issues on older iOS devices (typically iOS 5 through iOS 10) . Why These Certificates Are Needed

Manual Trusting
After installation, you must go to Settings → General → VPN & Device Management, find the enterprise profile (usually named something generic like “Shanghai Hongquan Technology Co., Ltd.”), and tap “Trust.” This manually overrides Apple’s security.
